As shown by the Figs. 7 and 8, the flange of the cap is provided withone or more tongues 50. As indicated previously, the sealing devicecomprises a sleeve with an annular groove having atapering side wall 48-and a tapering bottom portion 52.

v The bottom portion is provided with one orm'orere oesses53corresponding to the number ottongues of the capand suitably disposed.The annular side wall 48 is provided withcorresponding projections 54adapted and press on an opposed tongue oi' the cap. The upper part ofthe projection 54 is preferably b'eveled as at 55 joining at itsupper'edge 56, the upper edge line 57 of the side wall 48 :heseprojections 54 may be formed integralwith the side wall 48 of the grooveor may be constituted by added parts 58 adequately secured to thesleeve. With said device, flange of thecap 'willbe compressed itsperipheral extent, except where the tongues arelocated; these latterwill receive a lateral compression from-the projections 54 so as toforce them in the desired position against the flange of the cap. Afterthe sealing operation the cap presents itself in a general form shown ining of? one or morertongues will'release the sealing grip of the cap onthe receptacle and permit the removal ofthe closure.
